Hi Erica! I'm using an Ashford table loom, so the treadling for me would be the liftplan, right? I have an old version of fiberworks to use for drafting, but it doesn't have much in terms of fabric simulation (just the most basic). Thanks, I'll have to check out that group!

Ahh, great point! I have not yet had to move heddles from one shaft to another on this loom, but I can imagine it could be nightmarish! I hadn't even thought about having enough heddles if I used less harnesses. Thanks for the tip :) I'll definitely pay attention to that. You may have just helped me avoid a lot of trouble!
